I've been following a discussion on the apparent lack of JavaScript and Java on Android browsers. One of my hot button applications requires either JavaScript or at least the ability to run a .jar file in order to save data. No one in the other discussion has been able to find a Android browser capable of supporting this application (TiddlyWiki)..

View 2 Replies View RelatedFor a site I'm working on I'm implementing image preloading with javascript however i most certainly do not want to call my preload_images() function if someone is on slow bandwidth.
For my market the only people with slow bandwidth are those using mobile Internet on a smartphone.
What's the best approach for detecting these users so i can avoid image preloading for them?
option 1 : detect browser width
if($(window).width() > 960){ preload... }
option 2: detect user-agent with a list of browser to preload for
if($.browser in array safelist){ preload... }
are there any better options?
I believe that it's possible to call Java methods from (PhoneGap) Javascript. Anyone knows how to do that?? (I know how to do it by changing the source code of PhoneGap, but I'd avoid that)
View 3 Replies View RelatedI am currently trying to integrate a live search functionality in android. I use a customized Autocomplete widget. The widget itself provides me with a threshold to only start a query after a certain amount of characters have been typed in. But what I also want is that a query only starts, say if a user has stopped typing for 2 seconds.
As I load my contents with a AsyncTask I tried blocking the doInBackground function by calling Thread.sleep() right at the beginning. If the user would then continue typing the program would look after an existing task, cancel it and start a new one. This was my idea. But it doesn't quite work the way I expected. Sometimes it sends out queries even if the user is still typing, sometimes queries are canceled after the users stopped typing. Do you have any ideas on this or maybe a better way to solve this? Here are the code snippets:.....................
I am writing a hybrid web/native app and ran into issue. My app downloads a music file via Java code, and needs to update a Javascript download progress bar in the WebView in real time.
My understanding is the only way to call Javascript from Java is via the WebView's loadUrl method.
CODE:................
I have found that there is a significant lack of documentation of WebView's ability to communicate with Java via WebView.addJavaScript() method. First, the debug document http://developer.android.com/guide/developing/debug-tasks.html#Debugg... appears to no longer work. Second, what object types should we expect when going to and from JavaScript. I have done some trial and error and it appears that complex types can cross the boundary, for example java.util.Vector. However when a Java method returns a byte array to JavaScript it has a type of undefined and I have been unable to coerce it to any other type. Finally, there is great potential with this interface and with some more attention we could go far.
View 2 Replies View RelatedWhy below code is throwing nullPointer exception in last line (when accessing javaInterface.mValue) This line through NullPointer, so basically it is not being set. even though the javascript is correct and has been verified using FireBug that it returns expected string.
There are few lines above this code chunk but it is irrelevant this problem
CODE:................
I made a webview.addjavascriptinterface(geo, "geo"); to access the geo class from javascript, and, in the html-javascript I write: --------- function successCallback(p){ document.write("helo"); }

View 1 Replies View RelatedI have the pre installed browser and a week ago installed Skyfire the app that will play SOME flash content. Whenever I go on certain websites like Facebook, it will ask me which browser to use. So I select one, then the box comes up every couple seconds asking me to choose which browser to choose after I already selected one of them! This is so frustrating some times! I don't want to make skyfire my default since its still in Beta stages.
View 16 Replies View RelatedIs it possible to pass a JavaScript object from JavaScript to Java using addJavascriptInterface()? Something along these lines: var javaScriptObject = {"field1":"string1", "field2":"string2"}; JavaScriptInterface.passObject(javaScriptObject); How would such a call be captured on the Java side? I have no problem setting up the interface to send a string, but when I send an object, I receive null on the Java end.

View 3 Replies View RelatedI got the OTA 2.2 update pushed to my first generation Verizon Droid this morning. Nice new homescreens, love the apps menu, USB tethering option even showed up in my settings menu as selectable. BUT, nether my Dolphin Browser HD or the stock browser can connect to the Internet via 3g anymore (they work on WiFi though). It worked fine before the update. After TWO hours on the phone with Verizon (one Customer Service guy and two Tech support guys, one of those a "Droid support" person), their solution: Factory Reset to 2.1 and don't update it if it asks again. All other 3g Internet based services work fine: SMS, Facebook, Marketplace, News apps, etc. I mean COME ON Verizon! "The glitch is with Froyo and our mobile network but there's really nothing we can do". "The update is pushed by Motorola" "There is a second OTA update supposed to be coming in early September" Folks, is this 2.2 update really this faulty? Or is this maybe just my particular phone? I was also having an issue with my GPS no longer working for several weeks before the update. They couldn't figure anything out for that so they agreed to send me a new phone, which they said will have 2.1 on it. Since I'm traveling next week, I am reluctant to accept another OTA update. Any opinions about whether I should?.......
View 15 Replies View RelatedYou are all likely going to laugh at this, and I admit, you have every right too. For the first time today I am trying to enable the wifi on my droid when I am at home and have been unable to get it to work.
I turned it on, connected it to my home Wifi, used the correct password, and it says it is connected, and has been assigned an IP addressed. However, it isn't connecting to any websites or anything else in any of the browsers.
I have tried both the native and dolphin.
I'm making an Javascript web app and I can't for the life of me get the touchstart event to fire. I get the touchmove and touchend events no problem. This is a problem because as I see it the best way to distinguish between a tap and a scrolling motion is to zero a counter on the touchstart event, update it at touchmove and then compare it at touchend. I'm doing this so I can do some action at the end of tap but not a scroll. For instance, it would be very confusing if a page opened for an item in a listed after you finished scrolling down that list, but it would be nice to be able to tap on an item to open its page.
This is what I have..
I never see the touchstart alert. If I scroll the touchend will fire and app__touchMoving will have some sort of decent value. On a side note, I've noticed that sometimes the touchend will seem to fire multiple times.
Am I missing something basic here? Plenty of people say that this should work just fine on Android (and iPhone) yet the first listener never seems to fire.
Update: I should mention that I've been testing on a Samsung Galaxy S running Android 2.1.
I am trying to set the value of a global variable from Android code..

View 2 Replies View RelatedSo I'd been using the default for the first few weeks I had the phone. Then I moved to Dolphin. Dolphin has been a little spotty lately, so I did a quick search to see what, if any, others are out there. That brings me to xScope 2.5. Right now, it doesn't have many features. You can't open something in a new tab or window, for instance. There's no long-press functionality for links and pages yet. But it's lightweight, fast, and has a flawless pinch-to-zoom. For now, I'll be foregoing features for the sake of having this browser work smoothly and quickly. Anyone else tried it? I ponied up the $3 for the full version.
